WASHINGTON, Sept 10 (Reuters) - Domtar Inc. (Toronto:DTC.TO - news), a Canadian paper and pulp and wood company, filed on Monday with the U.S. Securities and Exchange Commission to sell up to US$600 million in notes. The Montreal-based company, Canada's largest maker of specialty and fine papers, plans to use the net proceeds from the offering to repay the $600 million, 12-month bond bridge loan for the purchase of four pulp and paper mills from Georgia-Pacific Corp. (NYSE:GP - news). Domtar plans to use any remaining proceeds to repay debt incurred to finance the remainder of the acquisition, the filing said. The note offering will be handled by J.P. Morgan.
